Answer:

The perimeter is 18.

Step-by-step explanation:

The first side is 5 units, the second is 5 units, the third is 2 units, the fourth is 2 units, the fifth is 2 units, the sixth is 1 unit, the seventh is 1 unit, and the eighth is 2 units. 5+5+2+2+2+1+1+2=18. When add all of them together you get 18.

Answer: Experimental Probability

Step-by-step explanation:

Theoretical Probability is the theory behind probability. Experimental (empirical) probability is probability calculated during experiments, direct observation, experience, or practice. The empirical probability, relative frequency, or experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.

Simplify 5^2 • 5^4<br> O A. 5^8<br> O B. 5^6<br> O C. 5•8<br> O D. 5^2

amid [387]

Answer:

Option B

Step-by-step explanation:

Given the following question:

$5^2\times5^4$

In order to find the answer, we simply apply the exponent rule and add the exponents.

$5^2\times5^4$
$2+4=6$
$=5^6$

The answer is option B or "5^6."

Hope this helps.

Y=(x-4)/(x*x)-11x+28

klio [65]

Y=(x-4)/2x-11x+28
y=(x/2x)-(4/2x)-11x+28
y=0.5x-2x-11x-28
1. subtract like terms
2. add 28 on both sides
3. so on and so forth...

Haley makes earrings and packages them into cube boxes that measure 1/6 foot wide. How many 1/6 foot cubic boxes can she fit int

alexandr402 [8]

Answer: 28 cube boxes.

Step-by-step explanation:

The volume of a cube can be found with this formula:

$V_{(c)}=s^3$

Where "s" is the lenght of any edge of the cube.

You need to find the volume of a cube box:

$V_1=s^3=(\frac{1}{6}ft)^3=\frac{1}{216}ft^3$

To find the volume of the shipping box, first we must convert the mixed number to an improper fraction. To do it, multiply the whole number part by the denominator of the fraction and add this product to the numerator.

The denominator does not change.

Then:

$1\ \frac{1}{6}=\frac{(1*6)+1}{6}=\frac{7}{6}$

Knowing the dimensions of the shipping box, you can calculate its volume by multiplying its dimensions. Then, this is:

$V_2=(\frac{7}{6}\ ft)(\frac{1}{3}\ ft)(\frac{1}{3}\ ft)=\frac{7}{54}\ ft^3$

Finally, in order to find the number of cube boxes can Haley fits into a shipping box, you must divide the the volume of the shipping box by the volume of one cube:

$\frac{\frac{7}{54}ft^3}{\frac{1}{216}ft^3}=28$
